Have you wondered how information from physical devices in the real world gets communicated to Smartphone processors? Do you want to make informed design decisions about sampling frequencies and bit-width requirements for various kinds of sensors? Do you want to gain expertise to affect the real world with actuators such as stepper motors, LEDs and generate notifications?
In this course, you will learn to interface common sensors and actuators to the DragonBoard™ 410c hardware. You will then develop software to acquire sensory data, process the data and actuate stepper motors, LEDs, etc. for use in mobile-enabled products. Along the way, you’ll learn to apply both analog-to-digital and digital-to-analog conversion concepts.
Learning Goals: After completing this course, you will be able to:
1. Estimate sampling frequency and bit-width required for different sensors.
2. Program GPIOs (general purpose input/output pins) to enable communication between the DragonBoard 410c and common sensors.
3. Write data acquisition code for sensors such as passive and active infrared (IR) sensors, microphones, cameras, GPS, accelerometers, ultrasonic sensors, etc.
4. Write applications that process sensor data and take specific actions, such as stepper motors, LED matrices for digital signage and gaming, etc.

Terminology/Cheat Sheet (Beginner)

In this course, you will see a lot of new words and acronyms you might not be familiar with. If you feel comfortable with your knowledge of tech terminology, feel free to skip these lessons since they will not affect the overall integrity of the course. If you see something that you want to know a little more about, feel free to watch the video to gain insight on some basic concepts. We do expect you to know the majority of this material before going into the next module, we would recommend going through the lessons as a quick brush up.

Hello, again. In this lesson, we wanted to take some time to go over some important concepts that we feel will kind of strengthen your foundation throughout this course. Now, one of those concepts that I would say a lot of engineering students, especially electrical engineering students, computing engineering as well, right? >> Right. >> You're always drilled on this one law. It's called Ohm's Law. Now, there's a lot of really good resources online that talk about Ohm's Law. We are going to talk about it in a, I wanna say a higher level. >> Not too deep. We're not gonna provide crazy circuit problems or anything. >> We are, however, going to provide you with a really cool diagram that I used throughout my undergrad, and we're going to, I think, do one example, explain how Ohm's Law can be used in a very simple circuit. And then, yeah, and then the electromagnetic spectrum. >> Right, so the electromagnetic spectrum is something we need to cover because later on we're going to talk about the infrared sensors and whatnot, and that's important because- >> Yeah, no, so we're gonna talk about the electromagnetic spectrum, like he said, for infrared sensing, but you need to understand why infrared? Where is the visual light, and where is the infrared located? Why can't you see it? Why are we able to use it? You know, etc, so we're gonna talk a- >> The uses and whatnot. >> Yeah, the uses and whatnot. So we're gonna talk a little bit about the electromagnetic spectrum, and then, of course, Bluetooth, because that's one of the exciting projects we've got in this course. >> Right. >> [COUGH] >> Okay, later on we're gonna make a little Bluetooth remote. It'll be fun. Mess around with your Dragonboard through like another phone, or? >> Yeah, through like an application on your Android. >> Great. >> And then operational amplifiers. Now, all of these things we kind of covered throughout the course, so you're gonna see this all over again. Maybe more or less detail, but we thought, again, it would be fun just to kind of give you a crash course before everything starts, so stay tuned. We'll have some fun.
